Audi A1 AC Failure: Compressor Dies, Warning Light On

Having experienced similar car air conditioning issues with my 2015 Audi A3 gasoline model, I can share my repair details. The symptoms match exactly what happened, complete AC failure, compressor not engaging, warning light, and error code. Initially suspected a simple auto refrigerant leak, but diagnostic testing revealed a failed AC control module. The repair required: Full system diagnosis, Replacement of the electronic AC control unit, Recharge of the AC system with fresh refrigerant, Recalibration of the new control module, Testing all HVAC functions This was a serious repair that required specialized diagnostic equipment and programming. The automotive cooling system worked flawlessly after fixing the control module. The vehicle HVAC system issue wasnt related to normal wear and tear, but rather an electronic failure. For quality repair, look for shops that: Have Audi-specific diagnostic tools, Can properly program control modules, Offer warranty on electronic components, Perform complete system testing post-repair The AC compressor itself was fine, the control unit was preventing it from engaging. Always get a proper diagnosis before approving repairs.

Thanks for sharing your experience. Your AC unit issues sound identical to what happened to my Audi A1 last summer. The problem turned out to be the control module too, and the automotive cooling system has worked perfectly since the repair. Could you remind me what the final cost was for your fix? I want to compare since repair prices can vary quite a bit. Also, has your cooling system given you any trouble since the control module replacement? My auto AC repair has held up well, but I keep watching for signs of refrigerant leaks just in case.

After getting the air conditioning repair done at the shop, I can confirm the total cost came to 980 Euro for replacing the defective control unit. The refrigerant compressor failure was completely resolved once they fixed the electronic control module. The vehicle HVAC system has worked flawlessly for over a year now with no signs of any cooling system problems or refrigerant leaks. The diagnostic testing confirmed it was purely an electronic control issue rather than a mechanical problem. The auto AC repair shop did a thorough job testing all components after the replacement. The price included the new control unit, programming, system recharge, and full testing to ensure everything worked correctly. Having proper AC function restored was worth the investment, especially since cheaper quick fixes often lead to recurring issues. No warning lights or error codes have returned since the repair was completed.

I really appreciate all the helpful feedback. After dealing with my AC unit issues, I finally got it fixed last week. The repair shop I chose did a full diagnostic and found the same control module problem. Total cost was 890 Euro, seems fair compared to what others paid. The auto refrigerant system needed a recharge after they installed the new control unit. They also tested for any potential refrigerant leaks and checked the entire vehicle HVAC system. The automotive cooling is working perfectly now, cold air blowing strong and no more warning lights or error codes. The shop I picked specializes in Audi repairs and had all the right diagnostic equipment. Much better experience than my previous mechanic. They even provided a 2-year warranty on the control module and their work. Glad I asked for advice here before choosing where to take it.
